I have a new MacBook Pro (November 2008) and i have been getting frequent kernel panics and screen glitches doing the most common activities, like going on Safari of iTunes. I then noticed this only occurs when I'm using the Nvidia 9400M processor. Last night i had three kernel panics (the last two within 10 minutes of each other, and with screen glitches) and all i was doing was Quick Looking videos. I recreated the kernel panics a few times by Quick Looking some high quality videos. Could it be that it has one of those faulty Nvidia chips? Are these indications of a faulty chip? Attached is a URL to a YouTube video I posted showing the screen glitches.
